Jayapura City (Indonesian: Kota Jayapura) is the provincial capital of Papua, Indonesia. It is situated on the island of New Guinea. It is situated on Yos Sudarso Bay (formerly known as Humboldt Bay). It covers an area of 935.92 sq.km, and borders Jayapura Regency to the west, Keerom Regency to the south, the nation of Papua New Guinea to the east, and the Pacific Ocean to the north. It had a population of 256,705 at the 2010 Census;[1] the latest official estimate (as at January 2014) is 315,872.

From 1910 to 1962, the city was known as Hollandia and was the capital of a district of the same name in the northeast of West New Guinea. It was briefly called Kota Baru and Sukarnapura[3] before assuming its present name in 1968. The literal meaning of Jayapura, as of Jaipur in Rajasthan, India, is 'City of Victory', Sanskritjaya: "victory"; pura: "city"). The reason for that name is that Suharto wanted to mention his victories while fighting Operation Trikora against the Netherlands. The last battle was fought in Jayapura during 14 August 1962 till 15 August 1962. Nowadays the Humbold bay native called the city as "Port Numbay".

In 1945, the Dutch made Hollandia the capital of Netherlands New Guinea. After the territory was handed over to the United Nations, on 1 October 1962, the city became known by the Indonesian name Kota Baru, and retained the name when Indonesia took control, on 1 May 1963. The city was briefly renamed Sukarnapura, after President Sukarno, until the end of 1968, when it acquired its present name.

On 12 May 1949, the Apostolic Prefecture of Hollandia was established in the city. In 1963, it was renamed as the Apostolic Vicariate of Kota Baru. In 1964, it was again renamed as the Apostolic Vicariate of Sukarnapura. It was promoted in 1966 as the Diocese of Sukarnapura, renamed in 1969 as the Diocese of Djajapura, and finally renamed in 1973 as the Diocese of Jayapura.

^The spelling SukarnApura was because Sukarno is a Javanese name which many endings include O, and when Indonesians wanted to call the city after his name as Indonesian based on Malay suffix A, sukarno's name within the city's name was altered to include A.
